Drop-in Cr⁶⁺ replacement
Zero equipment modification for immediate REACH compliance
Passivation · Process-engineered chemistry
Direct Cr⁶⁺ Replacement with Zero Equipment Change
01 / Product brief
Chromium-free post-phosphate passivation sealer based on zirconium or organic sealant chemistry. Seals the phosphate crystal structure to achieve 120–200 hours salt spray performance without REACH or EU ELV restriction. Validated as a direct Cr⁶⁺ replacement for automotive pre-treatment lines.
Validated for direct Cr⁶⁺ replacement with zero equipment change — allows phosphating lines to achieve EU ELV compliance without capital investment in new rinse tanks or dosing systems. Zero Cr⁶⁺ in effluent immediately from switch date.
02 / Performance
Product-specific outcomes for production quality, operating control and line performance.
Zero equipment modification for immediate REACH compliance
Strong corrosion performance without hexavalent chrome
Full compliance from day of chemistry switch
04 / Process position
Applied at Stage 6 (Passivate) — direct drop-in replacement for Cr⁶⁺ sealers delivering EU ELV compliance with no tank changes or line modifications.
